Article summary

Messages in Inbox can be marked as Junk and automatically routed to the Junk folder upon receipt through spam filtering or by configuring a Message Inbox rule.

Spam filtering

Messages that come into Inbox that meet a number of common spam indicators are generally routed directly to the Junk folder in Inbox.

A combination of criteria may cause an email to be routed to Junk, such as:

  • Subject lines that are written in all caps

  • Content that includes a disclaimer about spam: "We're not SPAM!"

  • Image-only emails

  • Use of the word "free" in the subject line

  • Use of odd characters or numbers in words ("2day," "gre@t!").

Best practice

Work with your IT department to filter spam before it arrives to your email account and is forwarded into Slate. This significantly reduces the amount of junk mail that comes into Inbox.
